PAPER FASTENER.

Application filed July 6, 1920.

Serial No. 394,277

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313;)

To all whom it may concern:

Be it known that I, CHRISTIAN Srnunn, architect, a citizen of the Republic of Germany, residing at Erlenbach, in the Canton of Zurich, Republic of Switzerland, have invented certain Improvements in Paper Fasteners (for which I have filed applications in Switzerland Feb. 28, 1919, Patent No. 83,510, and in Germany fvlarch, 1920), of which the following description, in connection with the accompanying drawing, is a specification, like reference characters on the drawing indicating like parts in the several figures.

This invention relates to a paper fastener adapted to fasten together a number of sheets of paper to form a booklet, and also to close paper-bags, sample, value and money parcels and to aflix address labels to pieces of luggage, etc.

One embodiment of the invention is illustrated by way of example in the accompanying drawing, wherein Fig. 1 shows the device in plan, and

Figs. 2, 3 and t its application.

Referring now more particularly to Fig. 1, the piece of metal sheet illustrated in this figure is subdivided into two plates 6, a, separated one from the other by a folding line a, one (6) of said plates carrying two fastening branches 6 produced by two lateral notches d. Opposite to the root of these fastening branches the other plate 0 is provided with a slit f. Each of the two free corners of the last mentioned plate is separatedyfrom the other portion of this plate by a folding line 9.

The sheets of paper are fastened together or the bags, parcels, etc, closed as follows The fastening branches 6 are bent upwards and pressed one towards the other, whilst the two plates are bent one towards the other along the folding line a, as shown in Fig. 2. If, for instance, the sheets of a writ have to be fastened together, they are perforated and slid with the hole over the fastening branches 6 which have previously been bent upwards. Thereupon the plates are entirely turned about the folding line a enabling them firmly to embrace the paper. After this, the fastening branches are turned upwards and laid flat down until they rest on one of the plates. This stage of the operation is shown in Fig. 3.

Should one wish touse the fastener illustrated in the drawing as corner clip, the portion h remainmg between the notches (Z is bent inwards in such a way that the fastening branches 0 come to rest on the adjacent plate 6. Thereupon the corners of the other plate are bent upwards along the folding line g, the sheets of paper to be fastened together are placed with their corners slid one over the other against the bent up corners of the plate, these corners being turned down until they'rest on the sheets, and finally the two'plates are turned about the folding line a. and bent one towards the other, whereby fastening of the sheets is completely effected.

The opening in plate a could be a hole taking the place of the slit f. I

As described above, the paper fastener is adapted to be used ad libitum for fastening by folding or by perforation. One may also, in a given case,put a seal over a fastener used for closing a money parcel.

Having described the nature of my invention, what I- claim as new and desire to secure by Letters Patent of the United States is 2- 1. A paper fastener comprising two plates consisting of one single piece of metal sheet and adapted to be folded one on to the other, one of said plates carrying two fastening branches produced by lateral notches and provided for the purpose of firmly keeping in their reciprocal positions the plates folded one on to the other, by turning down the fastening branches.

2. One form of the paper fastener as claimed in claim 1, characterized by the fact that opposite to the root (it) provided between the two fastening branches an opening is slit in the plate (0), for the purpose of passing through this opening the fastening branches when the plates are folded one on to the other.

3. One form of the paper fastener as claimed in claim 1, comprising twofoldin lines each of which se arates one of the free corners of the plate provided with the opening from the other portion of this plate, for the purpose of being able to use the paper fastener as corner clip as well.
